To all 'i 'hom it may concern:

Be it known that I, LAWRENCE F. SNIVELY, :Jlfi, a citizen of the United States, residing at Glenside, in the county of Montgomery,

5 State ofPennsylvania, have invented a new and useful Tire-Clamp, of which'the followin is a specification. I

' y invention consists of means for-carrying and tightly clamping anauxiliary tire or other traveling surface as a. sheath upon a tire proper.

The invention is satisfactorily illustrated in the accompanying drawing, but the important mstrumentalities thereof may be 15 varied, and so .it is to' be understood-that the invention isnot limited td the specific details shown and describedt Figure 1 represents apartial. transverse section and a partial elevation o? a tire clamp embodying my invention. 1 Fig. 2 represents an elevation on an enlarged scale of one of the T-bolts employed. Referring to the drawings. 1 designates a portion of a spoke of'a wheel, and 2, the telly thereof. 3 designates the. rim of the wheel, the same being interposed between the felly 2 and the tire proper 8,'the ends of said rim having thereon inturned flanges 12 which are adapted to engage with the shoulders'li-l on the'terminal known in the art. 14 designates clamps composed of cross bars which are adapted tobe imposed on'the periphery of the telly 2and has on its ends the-loops 5 through whose limbs 15 and 16 are passed the shanks'of the T-bolts 4', which latter are providedlwith the tightening nuts 6 and 7 which are adapted to tighten against the opposite limbs of the loops 5.-

, Extending from the limbs 16 of the loops 5 are the legs 18'on whose terminals are the hooks 10 which are adapted to be-aneh ored on the flanges 12 of therim 3 and take firm hold of the same.- v 9 designates the auxiliary tire or traveling surface which .is placed around the tire 8, and has on its exterior near its termlnalsthe grooved shoulders 11 with which engage the heads 17 of the T-bolts 4, the shanks. of the latter passing through said shoulders and also the limbs 15 and 16 of the loops 5 as has been stated; i

Itis evident that when the parts of the Specification of Letters Patent. I Patented llllay 115, 119117. git iibatihvm an 25, 1916. Serial No. 111,190.

device are assembled, therim 3 retains the tire 8 in position, and the heads of the bolts 4 take hold ofthe auxiliary tire 9. Then the nuts 7 are tightened against the limbs 15 of the loops 5, thereby drawing the heads 17 of the bolts 4 against the shoulders 11 of the upon the tire 8' holding the former firmly and immovably in place.

The nuts 6 are then tightened whereby owin to the opposite nuts 7, the legs-1S are tight y anchored on said rinr 3, thereby firmly locking the clamp 14: to the rim 3 and the felly 2, and so firmly holding the auxiliary tire in position, attention being directedto the fact that as the clamps 14 are firmly auxiliary tire 9, closing said tire 9 tightly anchored on the fixed rim 3, said clamps are firmly held in position on the fol 1y 2, and so I claim as new and desire to secure by Letters Patent, is

1. In a wheel tire, a rim, an auxiliary tire Y ,adapted to be seated over the tire proper, a clamp bridging the rim and means carried 'by and adjustable in the clamp for engaging the, auxiliary tire, said clamp having means for engagement with the rim.

2. In a Wheel tire, a rim, an auxiliary tire adapted to be seated -over the tire proper, a clamp bridging the rim andhaving lateral portions, extensions of said lateral portions engageable with the rim, and means adjustable in said lateral portions for engagement with said auxiliary tire.

3. In a wheel tire, a rim, a resilient clamp bridging the rim, an auxiliar tire adapted to .be seated over the tire proper, and resilient means carried by said clamp for engaging, said rim and additional means can ried' by and arranged substantially parallel with the first-named means for engaging tire. v r auxiliary tire.
